She is the adopted daughter of Benkei Kuruma. She holds a secret about her origin due to a mental block that was present when Benkei adopted her. She forms part of the new Getter team alongside Go and Gai, piloting the Shin Getter-2.
She is truly the daughter of Professor Saotome, raised as a boy until she became amnesiac and Benkei took her in.
Her name and appearance are derived from Kei Minamikaze from the Getter Robo G manga. Otherwise, they are completely different characters.
